Daniel Radcliffe shows his dark side and his American accent in new Horns teaser trailer

The Harry Potter star goes through hell and grows horns in the first trailer for his new supernatural thriller

He may be used to dodging Hungarian horntails as Harry Potter, but Daniel Radcliffe is facing a very different spiky challenge in the first teaser trailer for supernatural thriller Horns.

The new film sees Radcliffe adopt an American accent to play Ig Perrish, a young man accused of killing his girlfriend Merrin Wililams (played by Juno Temple).

The trailer offers a fleeting glimpse of Radcliffe with horns growing out of his head. "No one is born evil," Radcliffe's voiceover muses, "but sometimes when you go through hell, the only way out is to walk deeper into the fire."
